application ined :my 5, 1907. serial No. 382,245.

To all whom 'it may concern:

Be it known that I, CARL E. LUNDGREN, a citizen of the United States,residing at La Crosse, in the county of La Crosse and State ofIVisconsin, have invented a certain new and useful Improvement inTerminals, of which the following is a specification.

My invention relates particularly 4to a terminal used in connection withelectrical conductors by which a device of its kind is produced havingmeans for supporting it rigidly and without breaking or becomingdetached from the conductor with which it is connected and the supporton which it is mounted.

Much trouble and annoyance are produced by electric terminals such asare used on magnet coils becoming broken or detached from the end piecesof the'spools or cores on which the coils are wound and such terminalsas have heretofore been used have usually become disconnected from theirconductors after being used but a short time.

The primary object of my invention is to overcome these objections in asimple and etiicient manner and by inexpensive construction.

In the accompanying drawings, forming part of this specification, Figure1 is a side view of a. spool on which a magnet coil is adapted to bewound showing my improvement attached thereto; Fig. 2 is an enlargedside view of a detail portion of the spool illustrated in Fig. 1 showingmy invention; Fig. 3 is a section. of Fig. 1 taken on the line X-X; Fig.4 is a plan view of my improvedterminal, 'and Fig. 5 is a view lookingat an edge of said terminal.

In the drawings A represents my improved terminal which consists in agenera-l way of a shank 2y and ahead 3 on one end of said shank. Thishead is provided with a pair of barbs 4, one barb being formed adjoiningeach edge ofthe shank and the inner edge 5 of each barb tapering orspreading downwardly and outwardly along the shank 2 forming spreadingpoints, the outer edges 6 of which are substantially parallel with theedges of the shank. These pointed barbs are adapted to spread outwardlyby means of their tapering edges as indicated by the broken lines inFig. 2 when the shank of the barb is driven or pressed into a suitablesupport. A spool 7 of insulating material and of usual construction isillusstrated in the drawings on which a magnet coil not shown, isadapted to be wound. An end S of this spool is provided with a pair ofopenings 9 through which the Shanks of a pair of terminals are passed,their barbs being driven into4 th'e end and spreading and lockingtherein. In this manner the terminals are firmly supported upon thespool. In producing my improved terminal the barbs are formed b vsplitting the end of the shank, the entire device being stamped or cutout of a single piece of material.

In use, after the terminals have been secured upon an end of the spoolas described, the conductor of the coil is soldered or otherwisefastened to the terminals in the usual manner.

It is obvious that this invention is applicable as an electricalterminal to various electrical devices and the construction described isnot limited for use in connection with magnet coils, but may be appliedto electric circuits in general where a stationary electrical contact isrequired.

In accordance with the patent statutes, I have described the principleof operation of my invention, together with the apparatus which I nowconsider to represent the secured uporrny support. `by :L drivingmovevert into the. support as Suid points are mout, voluprising, u shankhaving its end driven into el'lgogement therewith.
